How it works

clock: clocks out character columns or shifts in data. din = 1111111: show characters and bitmaps column by column. din = 1xxxxxx shift in ASCII character x. din = b10xxxxx : shift in bitmap column xxxxx

How to test

Shift in some data and set din = 1111111 to clock out characters and graphics
